Description :
1. The module uses genuine quality relay , normally open interfaces Maximum load : AC 250V/10A, DC 30V/10A;
2. Using SMD OPTOCOUPLER isolation , driving ability , stable performance ; trigger current 5mA;
3. The module has a 24V working voltage options ;
4. Each way module can be set high or low triggered by jumper ;
5. Fault-tolerant design , even if the control line is broken , the relay will not operate ;
6. The power indicator ( green ) , 4 relay status indicator ( red )
7. Interface design humane, all interfaces can be connected directly via terminal wiring leads , very convenient
8. Module size : 73mm * 50mm * 18.5mm ( L * W * H )
9. Has four mounting bolts holes , hole 3.1mm, 67mm * 44.5mm pitch
Interface :
1. DC +: positive power supply ( voltage required by the relay has 24V option)
2. DC-: negative power connection
3. IN1-IN4: each way based on the settings , can be high or low to control the corresponding relay
Outputs :
12- line interface, the interface can be directly connected to all leads , user-friendly
1. NO1 - NO4: normally open relay interfaces , relay before the vacant after the pull shorted with COM
2. COM1 - COM4 Common Interface Relays
3. NC1 - NC4: normally closed relay interface relay shorted with COM ago , after the pull- vacant
High and low trigger selection:
1.S1-S4 in order to relay a way -4 road high and low trigger selection ;
2.Com with low short circuit , triggering the corresponding relay is low , while the high end of the short com high trigger
Package Include:
1* HiLetgo 4CH 24V Relay Module

I am installing a new fuel oil furnace and need an interface board to drive my electrostatic cleaner and my UV lights when the fan runs without putting stress on the furnace circuit board. This will do the trick. I will order another for a spare.

Hooked the relay board up and all relays worked...no issues. It's also nice to be able to trigger the relays with either a high or low signal. Plus, it's a small form-factor for four (4) DPDT (Form-C) relays.

Bought this even though it had numerous reviews saying some of the relays didn’t work which was a mistake, plugged it in like normal and relay 4 didn’t do anything to my surprise. The light came on so I knew my button was working and checked the connections they were just fine, went through every relay and none of them worked… im pissed to say the least I’ve gone over it a hundred times and even swapped it out with my old ones and they work just fine. This is just a crappy product all around which was super disappointing I was very exited for it

The product seems great, with all features one can ask fo.....r but the switching is not happening even with direct dc at input side for a given channel. Looks like this is a faulty relay case.

Received this board and tested it out. One of the four channels was non functioning. The board itself requires a very high level of current in order to trigger, so triggering from a microcontroller is actually fairly difficult. There are other relays out there that use transistors that can trigger on as little as 1mA. Find one of those instead!
